![Google summer of code
• Offers student developers stipends to write code for various open
source software projects.
• accepted students are paired with a mentor[s] from the participating
projects, thus gaining exposure to real-world software development
scenarios and the opportunity for employment in areas related to
their academic pursuits.
• more source code is created and released for the use and benefit of
all.

Contributing to Open Source
- 1. Contributing to Open Source Why, How, and Aah .. :) Amol A Sale [email protected] 1
- 2. Outline Who runs open source projects? Why open source? Business models Contributing to open source. Why to contribute? What benefit student or professional gets out of it? CMS, Desktops, Cloud, virtualization software. Business and productivity. Case studies: google, Facebook , twitter etc. Different ways to contribute to ubuntu to linux kernel to google chrome OS to firefox to wikipedia Resources 2
- 3. What is open source exactly and why it exists? Wiktionary definition: • “The practice of providing open-source code for a product; Open-source software in general; To make open-source” • free sharing of technological information like cooking recipes have been shared since the beginning of human culture. Sharing cooking recipe does not mean sharing cooked food. 3
- 4. Why open source? • Making Linux GPL'd was definitely the best thing I ever did. • Linus Torvalds • FLOSS potentially saves industry over 36% in software R&D investment that can result in increased profits or be more usefully spent in further innovation. • No code is good code, there is always scope for improvement and human limit may restrict the growth of your project, so open the source. • To make your code world class. • Open source software projects may offer a learning opportunity those students aren’t getting in school. • The best run open source projects have real standards, and teams of experienced programmers. 4
- 5. Who is doing it? 5
- 6. 6
- 7. 7
- 8. Why they contribute? • Companies like IBM, Intel, SGI, MIPS, Freescale, HP, etc. -- to ensure that Linux runs well on their hardware. • Distributors like Red Hat, Novell, and CentOS, Ubuntu have a clear interest in making Linux as capable as it can be. • Companies like Sony, Nokia, and Samsung ship Linux as a component of products like video cameras, television sets, and mobile telephones. • VMWare - built on Linux kernel. • Nvidia – Interested in Graphics business. • Intel – Processor family interest • Google – Run many Linux based servers in house. • Volkswagen? 8
- 9. What do I get as a student out of it? You get : • Chance to interact with world class software team. • Chance to modify or improve world class source code. • Come out with better skills than students who only do the required class work. • Learn from professionals. • Build your resume stronger. • Learn project management. • Learn ins and out of Source code. 9
- 10. How do I Get Started ? • Choose an area of your interest. • Do your homework -- mailing list(s), a wiki, code repository; things done in the past, things discussed on mailing list. • "Be familiar with coding style, contribution practices, community email etiquette, and copyright assignment practices for the project you are contributing to." "Most of all, have fun! Don't be discouraged by strong personalities in the community and try to understand other people’s perspectives. " • Reviewing code -- any competent developer appreciates more eyes on the code. • ASK questions • Documentation as a comments inside source code • Embedded Linux -- hot area for developers. • Don’t forget to understand licensing. 10
- 11. Business models • Open source software can be sold and used commercially. • Donations? • Saas? Iaas? • Thought there are FOSS apps around developed by big companies, Open source does not always means free of cost. • You can charge/sell your software along with source code. • You can distribute it free and charge for Support. • Important: First understand the Licensing in depth and then go with business. 11
- 12. Few Examples • Canonical Ltd. offers Ubuntu for free, while they sell commercial technical support contracts. • Mozilla Foundation have a partnership with Google and other companies which provides revenue for inclusion of search engines in Mozilla Firefox. • MySQL is offered for free, but with the enterprise version includes support and additional features. • Novell offers openSUSE for free through the openSUSE Project, while selling SUSE Linux Enterprise (SLE). • Red Hat offers the Fedora for free through the Fedora Project, while selling Red Hat Enterprise Linux (RHEL). • Oracle offers OpenOffice.org for free, while selling StarOffice. 12
- 13. Examples contd … • Zend Technologies offers Zend Server CE and Zend Framework for free, but sells Zend Server with support and additional features. • Wikipedia – Runs of donations. Sharing what we know for free. • KQInfotech's ZFS port to Linux • Infibeam? 13
- 14. So do you … • ..use good quality FOSS every day? • ..like the freedom and openness of the Internet? • ..think that Internet content should remain free? • ..share stuff with your friends for free? BUT • Did you know that all (a lot) of this stuff is based on... FOSS ? 14
- 15. Hey, Come on! These are all big MNCs selling/supporting open source software, what is there for a student like me? 15
- 16. Prodigies? 16
- 17. So how you too can be one among them? • Come up with a distinctive practical idea. • See if there is any work done towards it in open source projects. • If yes, See how can you adopt it and make it compatible with your idea? • If not, start a new open source project • Every tool is available there starting from kernel, filesystem to web server, open source social network platform find ways to adopt it to your idea. • CMS (Content Management Systems) – Drupal, Wordpress, Open Cart, MediaWiki and many more. • Open Source consultancy to SMEs or individuals. • Open source training. • Hosted Services – Cloud, Virtualization based infrastructure. • Saas or Iaas 17
